How much ready mix concrete you need?

How to use ready mix cement? Multiply the length times the width times the complexity of the gap or location you want to fill. This will give a cubic size, or volume, of concrete that you required. Next, divide the volume (in cubic feet, meters, etc.) by the package yield of the material you are consuming. Usually, premixed concrete available in 20, 40, and 80-pound bags, with the 80-pound bag yielding about 0.6 cubic foot of concrete.

You can use the Concrete Calculator and find out the ratio.
One of the most common places ready mixed concrete used is in foundations. Homes and small commercial buildings will regularly use poured concrete walls as the foundation of their structure.

Purchase the premixed item you have selected to use. Following are a few examples of different mixtures commonly available:

fast setting concrete
  • 3000 PSI (pounds per square inch) compressive energy, gravel, sand, and Portland cement mixture. This is a primary, reasonable concrete fit for most improvements, as well as for setting posts and poles.
  • 4000 PSI mixture is for restoring or constructing structural concrete like sidewalks or driveways, where additional strength will improve the durability of the glazed surface.
  • 5000 PSI fast-setting concrete is a very powerful mixture with a greater ratio of Portland cement to fine and coarse aggregates, typically you can apply where fast-setting concrete is helpful and higher strength required.

How to mix concrete by hand?

  • Spread a plastic sheet on the ground.
  • Measure out the materials.
  • Place the stone and sand into a pile on the sheet.
  • Place the cement on top of the pile of sand and stone.
  • Shovel the material in the pile to one side, creating a new pile and repeat three times.
  • Make a deep crater in the pile and add water.
  • Fold the mix in from the sides.
  • Continue to fold inwards and “chop” the pile to distribute water through the mix.

Prepare any forms you will need to hold the concrete, and grade and compact the soil or subgrade material. Place any reinforcing steel, and generally speaking, be ready for your concrete.
